shell shine by the seashore?

About this design:

pendant necklace with a beadmachine sepataria pendant, copper "cheaty-bail" and beads, brass and brown lip shell. This started as a bit of a lark. I was uncertain about the brown lip shell pieces, but I really like the way they coordinate with copper and brass. The shell pearlescence picks up a bunck of metallic colors - great for those multi metal pieces
